DTO stands for Data Transfer Object, which is a design pattern. It is one of the EPA patterns which we call when we need to use such objects that encapsulate and aggregate data for transfer. A DTO is similar to a data structure, but like a data structure, it doesn't contain any ...
The Data Transfer Object pattern is typically used in conjunction with a coarse-grained Remote Facade to reduce the number of remote calls. Mapper [Fowler03]. A Mapper is the recommended technique to load the DTO with data elements from the domain objects. Value Object. Some books refer to ...
Implementing the Data Transfer Object PatternThe previous two chapters discussed mechanisms for optimizing a client's use of a Web Service. You will find that, in practice, Web Service operations are relatively expensive when compared to a local method call between objects in the same process. ...
The Sun/Java community's use of terminology has changed since the book was published. They switched to using "Transfer Object" as the name for this pattern. Consequently "Value Object" became regularly used in the way that I describe in this book. What is the point of using DTO (Data Tr...

带你见个新朋友,轻松掌握DTO(Data Transfer Object) 现状 对于分布式系统,需要在不同系统之间传递与转换域对象。因为我们不希望外部公开内部域对象,也不允许外部域对象渗入系统。传统上,数据对象之间的映射通过手工编码(getter/setter)的方式实现,或对象组装器(或转换器)来解决。我们可能会开发某种自定义映射框架来满足...
to the Web service. This reduces the overhead associated with two separate calls and allows you to use a single connection with the database to retrieve both the recording and the track information. For a detailed description of how this improves performance, see theData Transfer Objectpattern....
A DTO's only purpose is to transfer state, and should have no behavior. See Martin Fowler'sexplanation of a DTOfor an example of the use of this pattern. Here's the difference:POCO describes an approach to programming(good old fashioned object oriented programming), whereDTO is a patternth...
// of Transfer Objects. } ... } The Customer Transfer Object class is shown in Example 9.5. This is used by the DAOs to send and receive data from the clients. The usage of Transfer Objects is discussed in detail in the Transfer Object pattern. ...
The Active Record pattern is similar to what you get from a LINQ-to-SQL object model (and the defaultgenerated model with the Entity Designer in the Entity Framework Version 1.0). Starting from an existing database, you create objects that map a row in a database table. The object will...
